Phase-pure iron pyrite nanocrystals for low-cost photodetectors

Oct 2, 2014 . Earth-abundant iron pyrite (FeS2) shows great potential as a light absorber for solar cells and photodetectors due to their high absorption coefficient (>105 cm-1). In this paper . Lastly, sulphur powder was added to the homogenous solution, which was magnetically stirred for over an hour. The final.

Pyrite - Wikipedia

The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's.

PaleoPortal Fossil Preparation | Pyrite "Disease"

Pyrite (or iron persulfide: FeS2), also known as “fool's gold,” is a common mineral that is often found in sedimentary rock. In some fossil deposits pyrite gets incorporated into bone, invertebrate shell, and plant fossils during the process of fossilization. If these fossils are exposed to conditions of high humidity, “pyrite disease”.

Investigations of Pyrite Nugget Beads: An Experiment for National .

Oct 13, 2017 . In yet another test, I placed the powder in a blow torch and plunged the hot material into water containing a small amount of base2 and phenolphthalein indicator. This was done to test for the production of H2SO4 in the reaction between iron pyrite, oxygen and water at high temperature:3.

Is Iron a Mineral or Rock - 911 Metallurgist

Mar 17, 2017 . If heated before B.F., sulphur fumes are given off, and eventually a globule of metal, attractable by the magnet, is obtained. The powder of iron pyrites is very slowly soluble in nitric acid. This ore carries gold in either a small or great quantity, and is generally to be found in gold-bearing and other lodes, oxide.
